General-purpose I/O ports
These ports are available only in the single-chip mode.
I/O pins for the lower eight bits of external data bus
These pins are available in an external-bus mode.
General-purpose I/O ports
These ports are available in the single-chip mode and in an
external-bus mode with the 8-bit data bus specified.
I/O pins for the upper eight bits of external data bus
These pins are available in an external-bus mode with the 16-bit
data bus specified.
General-purpose I/O ports
These ports are available only in the single-chip mode.
Output pins for external address buses A00 to A03
These pins are available in an external-bus mode.
16-bit reload timer 1 (ch.0 to ch.3) input pins
These pins are available when the 16-bit reload timer 1 (ch.0 to
ch.3) input specification is “enabled”. The data on the pin is read
as the 16-bit reload timer 1 (ch.0 to ch.3) input (TIN0 to TIN3).
General-purpose I/O ports
These ports are available only in the single-chip mode.
Output pins for external address buses A04 to A07
These pins are available in an external-bus mode.
16-bit reload timer 2 (ch.4 to ch.7) input pins
These pins are available when the 16-bit reload timer 2 (ch.4 to
ch.7) input specification is “enabled”. The data on the pin is read
as the 16-bit reload timer 2 (ch.4 to ch.7) input (TIN4 to TIN7).
General-purpose I/O port
This port is available in the single-chip mode or when the middle
address control register setting is “port.”
Output pin for external address bus A08
This pin is available in an external-bus mode and when the middle
address control register set to “address.”
General-purpose I/O port
This port is available in the single-chip mode or when the middle
address control register setting is “port”, with the PPG output is
disabled.
Output pin for external address bus A09
This pin is available in an external-bus mode and when the middle
address control register setting is “address.”
PPG timer output pin
